Other than the obvious (leafing out), what symptoms have you noticed of hydrangeas re-awakening?
Last year, my shrubs did not leaf out at all but the wild temperature swings resulted in very few blooms on unprotected macrophyllas (macs).
This year, I noticed leaf out only on the ends of the stems a few days back... which means that the flower buds will be killed if the silly thing does not go dormant again. I am hoping for a gradual descent in temperatures. So far, the long term forecast is favorable for this.
As usual, Oakleaf Hydrangeas were more hardy. Last year, they had no bloomage problems. This year, one finally went dormant but the other one still has a gorgeous display of purple-red-orangish leaves. It is normal for them to go dormant quite late here by the way, so I am no worried about their blooms... yet. Their flower buds have survived at times when temps tanked to the high 10s but the macs, ugh, ah the macs, eek, eh the macs....
I was wondering if someone had noticed a clue of this "awakening" that was not the leaf out? Would be nice to know in case Mother Nature decides to send much chillier temps this way. Winter protection is not something done all the way down here as out temps are normally mild in winter.
Merry Christmas y'all,
